Personally I'd rather pick 2k over NT 4.0 because 2k is more compatible with games.
That said, I'd prefer an nlited XP over 2k any day.

Ok... W2K it is.

What about a sound card? The board has two ISA slots.

You could use a Sound Blaster Awe64 which is great!

Ok, I presume it's W2K compatible? I haven't really found much info suggesting that it is. Also, probably gonna look for a gold edition, anything I need to look out for?

Yeah it should work fine under Win2000. Why an ISA card though? You could just get SoundBlaster Live and use soundfonts for midi music, but forget DOS, which you already should forget if you plan to use Win2K.

BP6 is Win2k compatible, I set one up a few months ago. I gather some people find it more stable with NT4 but I didn't find any stability problems. I did have some issues during the install but as I recall these were solved by loading the correct IDE drivers.

Interesting about the ISA slots, that board got me wondering why use ISA sound if you're running an OS that's capable of using dual-cpus. I guess the board was aimed at either people shifting to NT that might have legacy hardware, or was simply trying to appeal to as many people as possible [NT - got dual cpu, 95/98/DOS - got ISA].

I'd go with 2000, all the freakin way. It IS the greatest version of Windows ever made, after all. 😁

Well, 2 ISA slots were pretty standard on 440BX boards. In contrast, I think only one ISA slot were standard on the later KT133 boards (one of the last chipsets that used ISA instead of LPC).

The later 440BX mobos have 6 PCI and 1 ISA but the 6th PCI is a slave slot with no IRQ due to 440BX's limits. Good for a Voodoo card but I'm not sure what else...

I would definitely go Win2K. NT4 is pretty limited when it comes to gaming. Something like a dual PPro would be better off with NT4 though. 2K runs like pretty slow on a PPro (even a 233MHz 1MB L2 dualie).
